6 Claims. 1

The present invention relates to forms useful in pouring concrete to form curbs and foundation walls.

A general object of the present invention is to provide an improved supporting assembly for maintaining forms in a predetermined relationship to each other while concrete is being poured between them.

Another object of the present invention is to provide an improved assembly, characterized by its inexpensiveness, ease of manufacture and ease and convenience with which the individual parts may be assembled in the field in a minimum amount of time.

Another object of the present invention is to provide an improved supporting assembly of the character described in which all of the stakes anchoring the form are of identical construction to thus minimize the necessity for stocking or supplying different types of stakes.

Another general object of the present invention is to provide an improved concrete form supporting structure which may be quickly mounted in position and quickly removed without much efiort.

Another object of the present invention is to provide an improved concrete form supporting structure characterized by the fact that the stakes supporting the structure are adapted to directly contact the concrete form', tlius permitting the back form to be set as to line and grade, and facilitating the driving of stakes against such back form.

Another general object of the present invention is to provide a concrete form supporting structure useful in pouring curbs, characterized by the fact that only angle iron stakes on opposite sides of the form are required with but a single brace releasably secured to upper ends of the stakes on opposite sides of the form.

A specific object of the present invention is to provide an improved concrete form supporting structure useful in pouring curbs, characterized by the fact that it uses two angle iron stakes releasably secured together at their upper ends by means of a self-locking cross brace.

The features of the present invention which are believed to be novel are set forth with particularity in the appended claims. This invention itself, both as to its organization and manner of operation, together with further objects and advantages thereof, may be best understood by reference to the followingdescription taken in connection with the accompanying drawings in which:

Figure 1 is a perspective view of an assembly embodying features of the present invention;

Figure 2 is a sectional view taken substantially on the line 2-2 of Figure 1;

Figure 3 is a perspective View in enlarged form showing two elements of Figure 1 in detached condition;

Figure 4 is a' perspective view of a modified assembly embodying features of the present invention; h V

Figure 5 is a viewin enlarged form of the two parts shown in Figure 4 in detached relationship;

Figures 6 and '7 are perspective views showing the rear and front stakes, respectively, of Figure 4;

Figure 8 is a sectional view taken substantially on the line 8-8 of Figure 4.

Figure 8A is a perspective view of a bolt used in the apparatus,

In the two diiferent arrangements shown in Figures 1 and l, there is provided a pair of angle iron stakes on opposite sides of wooden forms with a self-locking cross brace releasably secured to the upper ends of the stakes. The forms shown in Figures 1 and 4 are intended primarily for use in pouring concrete curbs, and the arrangement shown in Figure l is my preferred arrangement since the front and back stakes Lilli and till, respectively, may be of identical construction and interchangeable, to thus avoid the necessity for stocking and supplying two different types of stakes. Referring specifically to the arrangement shown in Figures 1-3, both inelusive, the stakes iilfi and iii! of identical construction, are formed from angle iron stock and have their lower ends pointed to facilitate driving theminto the ground. One leg of the angle iron member lilii' has a series of apertured por-' tions EBA through which nails may be driven to secure the wooden planks or forms I82, I83 thereto; the other leg of the angle iron member we having a series of self-locking apertured portions liliiB therein; of generally triangular or tapered shape for cooperation with the locking lug i9 2 affixed to one end of the cross brace m5.

The cross brace I85 has a slotted portion 86 extending transversely and centrally thereof Lil through which a carriage "clamping bolt passes, with its square shoulder portion illlA cooperating with the apertured" portion lililB'to preventturning of the bolt when and as the nut till; in the fonnor atapped bent elongated. arm or handle, is {turned to tighten the clamp thus provided; Forthis purpose t'he ap ertured" portions lBilBin each of the stakes-ltd; it! are of 3 identical size and shape so as to cooperate respectively with the shouldered lug I04 on the brace I05, and with the square heads I'IA of the bolts 20? as shown in Figure 2.

Examining the general shape of the apertured portions IO0B in Figure 3, it is observed that they taper towards the lower or pointed end of the stake to provide an area of decreasing cross section in which the lugs I04 may become wedged with the shouldered portion of such lugs, as shown in Figure 2, overlapping the apertured portion I003. The same type of locking cooperation exists between the shoulder portion I0IA of the carriage bolt I07 and the identical apertured portion IO0B on the other stake I0I.

In the arrangement shown in Figures 4'7, the back stak I20 is of identical construction as the two stakes I 00 and IOI shown in the previous figures, with the apertured portions I20A and I203 therein serving the same purposes as the corresponding apertured portions IO0A and H103 in the stake I00 or corresponding apertured portions in stake NH. The front stake I2I is also of angle iron stock with a pointed end to facilitate driving the same into the ground, and has a series of apertured portions I2IA through which nails may be driven to secure the front wooden plank or form I02 thereto.

Stake I2I has mounted a shouldered lug I25 near the upper end thereof for cooperation with an arcuate slotted portion I26 (Figure in the end of brace I28, which otherwise is of identical construction as the brace I05 shown in Figure 1. The brace I28 has an apertured portion I28A extending centrally and longitudinally thereof through which the clamping carriage bolt I30 passes, with its shoulder portion cooperating with one of the apertured portions I20B in stake I20 to prevent its turning while the tapped handle IIO is turned to clamp the structure.

It is clear that the elongated slotted portions I06 and I28A in the braces I05 and I28, respectively, allow a considerable range of adjustment for curbs of different widths.

It is thus apparent that the arrangement provided in Figures 1-8, inclusive, eliminates the use of tie rods and spreaders heretofore used, and permits the rapid assembly of forms without the need of additional bracing.

It also permits the contractor to use thicker planks or forms I02, I03. customarily, such planks are one inch stock and with the present arrangement the forms may, for example, be of two inch stock with a greater distance between stakes to thus effect a saving in time and labor.

While the particular embodiments of the present invention have been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made without departing from this invention in its broader aspects and, therefore, the aim in the appended claims is to cover all such changes and modifications as fall within the true spirit and scope of this invention.
